Analysis of interaction of dynamically adjustable gyroscopes on elastic platform by finite-element method

The drift of a dynamically tunable gyroscope in the general case of spatial movement of the pedestal and its mutual influence with known analytical expressions for the eigenfunctions of the elastic platform is investigated. Gyroscope errors due to interaction in a dynamic system consisting of two different dynamically tunable gyroscopes and a platform are analyzed by using a finite-element approximation of the elastic platform as a shell. The finite-element method makes it possible to investigate the mutual influence of dynamically tunable gyroscopes installed on an elastic platform of an arbitrary shell type. The system reduction algorithm derived makes it possible to select the parameters of platform and to make a final analytical estimates of the interaction.
